IMPROVEMENT IN HINGES FOR SHUTTERS.

Specification forming part of Letters Patent No. 127,425, dated June 4, 1872.

SPECIFICATION.

To all 'whom fit may concern:

Middletown, in the county of Middlesex and State of Connecticut, have invented a new and Improved ShutterHin ge; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawingand to the letters of reference marked thereon.

This invention relates to that class of hinges which are designed especially for use upon shutters; and consists in providing the hinge with a locking'device arranged in a peculiar manner, by means of which the parts of the hinge are secured together against accidental displacement, and the joint is protected from the entrance of moisture, as will be described h erein after.

In the drawing, Figures 1 and 4 represent plan views of the supporting half ofthe hinge; Figs. 2 and 5, plan views of the half which is attached to the blind; Fig. 3, a sectional elevation of the contiguous parts of the hinge as united in a reversed position; and Fig. 6, a plan view of the hinge with its parts united.

To enable others to make and use my improved hinge, I will now proceed to describe fully its construction and the proper manner of using the same.

A represents the supporting half of the hinge, which is secured to the window-frame. It consists of the tapering-screw portion a, shoulder al, and ring a2, having a central orice, a3, with notches or recesses a4, as shown. The lower half of the ring is also cut out so as to form a recess, as shown at x, Fig. 3. B represents the half which is secured to the blind.

It consists of the tapering-screw portion b, ear b1, with pin b2 having projections b3 b3. These two halves are united by inserting the pin b2 into the central orifice a3 of the ring a2, the notches a4 permitting the passage of the projections b3. When the parts are in place the projections b3 move freely within the recess formed in the lower half ofthe ring a2.

It will be observed that these parts can only be united or separated when the screw portions are in the same continuous line. Hence, it follows that, when in use, the shutter cannot be removed either when closed or wide open, but only when half way between these points. This construction makes it almost impossible for the shutter to be blown up out of its socket by a blast of wind from beneath. The-peculiar construction and arrangement OI" parts also is such that the joint is protected from the entrance of moisture by the covering-ear of the upper half of the hinge.

The hinge is exceedingly simple in its con-
